Any explosion signifies the release of repressed anger or emotion of some type. The natural energy released shows the extent of how repressing emotions is not healthy. This type of dream explores the necessity of releasing feelings so you can be renewed and open to a changing world. In a dream, seeing the explosion of an atomic bomb and its threat of ‘radio-activity,’ can also warn of the psychological manifestation of physical symptoms due to the inability to recognize and process anger. An explosion is a positive sign that the past can be released so something new can grow in its place. See also Atomic Bomb.
